CAR TRUCK.

APPLICATION FILED 00?.10, 1907 3 SHEETS-SHEET 3.

The plates9, which serve as spring caps 4 and lower bearing plates for the lateral moas clearly shown in Figs. 1, 2 and 3.

lower side bearings 13, which straddle the top.

arch bars, as hitherto noted, are made of such size, in the dimension thereof lengthwise of the truck, that the ends thereof form upward extensions of-the vertical faces of the truck bolster, as best shown in Figs. 1 and 3; and hence, it follows that said side bearing brackets 13 may be treats as parts of the truck bolster in their relations to the bolster columns 4. The bolster columns 4 are extended upward beyond the top arch bars 3,

as described, so as to sustain said relation to From these relations ofsaid said parts 13. parts 4, 12 and 13, it follows that the forward and backward thrusts on the bolster 12 are delivered partly through the bolster roper and partly through the said bearing rack: ets 13; and these strains, so delivered, are taken by the columns partly above and partly below the top archbars This affords a good construction for takin the said strains to thebest advantage,'whi e, at-the same time, enabling the truck; bolster to be kept beneath the top arch bars and nevertheless have the requisite freedom for the de sired lateral motion and the required clearance for the vertical or. spring cushioned motion.

noted, itwil be seen ,thatf'inboth, thesaid Barber patent 863,012 and said'Lake and Deverell patent 798,350, the truck bolster had vertical or spring cushioned motion only, while-thelateral motion wasptaken on the truck bolster'through' the intermediate or'so-called floating plate located" between the lateral motion and the radial; motion rollers. It followed, of course, that the swiveling center plate membershad to be of such construction. as .to permit this lateral motion of the car body relative to the truck bolster, and. one or the other had to be slotted to give the clearance for the lateral travel 0 the king bolt.

efiords'arnore reliable and stable connection It is obvious that- --th1s3d1fficulty is overcome in the present.

erases for the most advantageous distribution of the strains. The advantage in this respect is the same as that set forth in my pending truck case filed September 30, 1907, under S. N.

395,114. It is there shown, however, as

realized in a girder-type-of side frames, and

is herein shown as realized in an arch bar type of side frames. The bearing surfaces of the plates 9 and 11 for the inter osed lateral motion rollers 10 are of the kin disclosed and'claimed'in Patent 784,096, granted to Lee Barber, of date March 7 1905,

and have all the advantages therein noted,

-What I claim is ,1.- In a car truck having side frames of the arch bar type, the combination with bolster columns rising above the toparch bars, of top arch bars passin through the said columns, and a truck b0 ster workin below the said top arch bars and provide with side bearings rising above the same and cofiperating therewith to distribute the forward and backward thrusts to the said columns, partly above and partly below the said top arch bars, substantially as described. I

. 2. The combination with arch bar side frames, of truck and body bolsters con' nected for swiveling motion in respectto each other, lateral motion rollers and radial motion rollers supporting the car body and. its load through the side bearings, with the truck bolster laterally movable below the-top arch bars on' -the lateral motion rollers and having fiXedthereto the lower bearings for the radial motion rollers with the same constructed to straddle the top arch. bars and aiiord therequisite clearance for the vertical and lateral motion of said bolsters, stantially as described.

3. The combination with arch bar side I frames, of truck and body bolsters con- Icmparin with the priniipatentsabove nected for swiveling motion in respect to. h

and afford the re uisite clearance for the.

vertical and latera motions of said bolster, and bolster columns rising above the top ,arch bars and receiving the forward and backward-thrusts partly from the bolsterv proper and partly from said lower side bearings fixed'thereto, substantially as described.

4. In a car truck havin side frames of the arch bar type, the com ination with the bolster columns 4 rising above the top arch bars, of the top arch bars 3 passing through the said columns, the bolster supporting i springs 8, the plates 9 with lugs 9 embracing said columns, the lateral motion rollers 10 on said plates 9, the truck bolster 12 having 876,566 A v a the plates lltresting on said rollers 10, with said bolsters 12 and 16, all for cooperation 10 said truok bolster located below the top arch substantially as described. bars and having the side bearings 13 strad- In testimony whereof I affix my signature dling the top aroh bars and workingbetween in presence of two witnesses.
